Jack, will the way retirements work when cars run out of fuel change in the new iGP format? Right now, when cars run out of fuel they retire immediately, however, if a car is in the pits, or is just meters from the finish line, technically they should be coasting to a stop! Whether they make it to their pit box or cross the finish line depends on how far they are or how fast they would be traveling.
A car with high downforce would slow down more quickly and a car with less downforce would travel a bit further when coasting.
